Review on 🔥 Grabber Toe Warmers - Extended Duration Natural Air Activated Warmers - Up to 6 Hours of Safe, Odorless Heat - 40 Pairs by Noah Trigg

EDIT: Revain is doing something sloppy - they are changing the link from the 'Orders' page to the product so that it no longer points to 'Revain LLC' as the seller and now points to another random seller. This results in the reviews going to another seller! When you buy from Revain LLC, open the package immediately. If the first package didn't take at least 6 hours, RETURN IT ALL IMMEDIATELY - don't wait to make sure the rest is ok. It's not like this. ORIGINAL REVIEW (purchased from Revain LLC): I only have 3 hours of this batch. Another batch from a different seller lasted a full 8 hours. Hence poor quality control and low consistency. Also the material is centered on one side as others have pointed out. You are taking a risk by buying them.
